TERMINAL-PROTECTING COMMUTATOR CASE.

Application filed November 17, 1923. Serial No. 675,340.

The object of the present invention is to protect the ends of the wires connected to the commutator case of the Ford motor. These connections are exposed to accumulations of oil, water, dust and dirt and are frequently injured by contact of the fan belt therewith, resulting in the wearing away of the insulation and the cutting through of the wire, all tending to cause misflring of the engine and an impaired motor.

The present invention provides protective means for the ends of the Wires connected to the contact posts of the commutator case which prevents oil, water, dust and the like from collecting on the connecting ends of the wires and prevent possible contact of the fan belt therewith.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the application:

Figure 1 is an elevational view of the inner side of a commutator case provided with protective means embodying the invention,

Figure 2 is a similar view of the outer side of the case,

Figure 3 is a side view thereof,

Figure 4 is a sectional view on the line 4-4 of Figure 1, and

Figure 5 is a sectional detail on the line 5-5 of Figure 2.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The numeral 1 designates the commutator case such as generally provided for the Ford motor. The case 1 comprises a conical portion 1 and a cylindrical portion 1. The case 1 is provided at the juncture of its portions 1 and 1 with axial and radial flanges 1 and 1 respectively, and the flange 1 is provided with diametrically arranged opposed IGCQSEBS 1. A ring or band 2 extends outwardly from the case portion 1 a short distance from the free edge thereof which rection of the flanges 1 and 1 A ring 4 is mounted upon the case and comprises angularly disposed elements, the one paralleling the ring or flange 2 and resting on the flange 1 and contacting with the flange 1. The flange l holding this ring element spaced from the ring 2 a distance to receive the contact posts 5 and ends of the wires which are connected thereto when the device is in service. The other member of the ring 4 encircles the case and is spaced therefrom a distance to receive the contact posts 5 and wires (not shown) adapted to be connected thereto and disposed to engage the said ring 2 and the inner side of the lip 3. The ring or flange 2 preferably forms a part of the commutator case 1, whereas the ring 4 is detachable and is provided with inwardly disposed lugs or ears 6 which are positioned in the recesses 1 and which are apertured to receive fastening screws 7, whereby the ring so is held to the case 1. The ring 4 is provided with a usual eye 8 to which the control rod (not shown) is connected in the usual way. The ring 4 is also provided with an outlet 9 which is preferably curved to give proper direction to the wires passing therethrough and which are connected to the contact posts 5 and disposed within the housing formed by the rings 2 and 4. The case is provided with the usual oiler 10 as shown in. Figures 2 and 3.

lVhat is claimed is:

In combination, a commutator case having conical and cylindrical portions and provided at the juncture of said portions with axial and radial flanges, said axial flange having diametrically opposed recesses, a band extending outwardly from said cylindrical portion adjacent the free edge thereof and provided at its outer edge with a lip exwith said radial flange and having the other element thereof overlying said cylindrical portion and contacting with said band and the inner side of said lip, ears extending in diametrically opposed relation from said first element and fitting in said recesses, and 10 ring retaining elements engaging the case and ears.

In testimony whereof I affix my signature.

JOSEPH E. PERTUISOT.
